Where to Add Car Antifreeze?

[Julian]

Car antifreeze is added to the radiator. You can locate the radiator cap by opening the engine hood. The steps for adding antifreeze are as follows: 1. Open the filler cap and then open the drain valve at the bottom of the radiator; 2. After the old antifreeze has completely drained out, add new fluid until fresh liquid starts to flow out, then tighten the drain valve; 3. Start the vehicle when the fluid level reaches the MAX mark; 4. Continue adding until the radiator is full. Car antifreeze is a specially formulated coolant containing additives, primarily used in liquid-cooled engine cooling systems to prevent the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head.

I used to add coolant by myself frequently, usually looking for it in the engine compartment. It's a semi-transparent plastic tank, typically visible after opening the hood, with a cap labeled COOLANT or something similar. The color is mostly green or pink, depending on your car model. Remember to always add it when the car is cold, as the high pressure in a hot engine can cause the liquid to spray out when opening the cap, potentially causing injury. It's best to check that the fluid level stays between MIN and MAX; adding too much can actually hinder the cooling system's performance. Generally, check it every six months, especially before winter, to ensure the coolant is at the right level to protect the engine from freezing and prevent corrosion, extending the lifespan of components. Avoid mixing different brands or colors of coolant, such as adding green to pink, as chemical reactions can cause clumps that block the pipes, sometimes even requiring replacement of the entire cooling system in severe cases. If you're unsure which type to use, just refer to the recommendations in the owner's manual.

I think the most crucial aspect of adding coolant is safety. It's located in a dedicated reservoir under the hood, shaped like a small translucent bucket where you can see the fluid level. I always wait for the car to cool down for several hours before operating, otherwise the high-pressure gas and hot air inside can cause burns. When adding, slowly unscrew the cap bit by bit to release pressure, then gently pour new fluid to the appropriate height without exceeding the MAX line. As a beginner, it's easy to forget the mixing rules, such as not mixing ethylene glycol-based coolant or replacing it with water, otherwise the system may freeze and crack the radiator pipes in winter. Make it a habit to check during seasonal transitions, like adding a bit in autumn to keep the system ready to protect the engine through winter and reduce maintenance costs. Don't forget to regularly inspect the reservoir area for any signs of leakage to prevent potential hazards.

I still remember the first time I added coolant when I was just learning to drive. It was in a small plastic tank in the engine compartment, with a clearly marked cap labeled COOLANT. With the engine cold, I opened it and added new fluid up to the marked line—not too much, not too little—to ensure the engine would work properly. This stuff doesn't just prevent freezing in winter, protecting parts from ice damage, but also prevents overheating in summer, extending the engine's lifespan. That's why regular top-ups are crucial. I'd advise beginners to check the manual for the exact location and inspect the level every three months, keeping it near the midpoint. Avoid mixing different types to prevent sediment issues. It's simple and straightforward—don't overcomplicate it.
